Read each question carefully and use inductive reasoning to determine the next item in a sequence, complete a pattern, or make a conjecture based on given observations. Show all your work where applicable.
1. Find the next two terms in the sequence: 3, 7, 11, 15, ,
2. Find the next two terms in the sequence: 1, 4, 9, 16, ,
3. Find the next two terms in the sequence: 2, 6, 18, 54, ,
4. Draw the next figure in the pattern:
5. Observe the following sums of consecutive odd numbers: 1 = 1 1 + 3 = 4 1 + 3 + 5 = 9 1 + 3 + 5 + 7 = 16 What conjecture can be made about the sum of the first 'n' consecutive odd numbers?
The sum is always an odd number.
The sum is always 'n'.
The sum is 'n' squared.
The sum is always an even number.
6. Make a conjecture about the product of two odd numbers. Then, provide a counterexample if possible.
7. Make a conjecture: 'All prime numbers are odd.' Provide a counterexample.
8. Inductive reasoning always guarantees a true conclusion.
True
False
9. Inductive reasoning moves from specific observations to general conclusions.
True
False
